en.Wedoany.com Reported - Recently, the "Qiaoyuan Hao," a new-generation twin-hull professional marine engineering survey vessel, was officially launched. This vessel is the largest of its kind in China, with leading comprehensive performance and intensive technological innovation. Multiple original technologies have addressed key technical bottlenecks, filling gaps in China's deep-sea high-end survey equipment. Its core supporting equipment, the marine drill rig, was provided by Hengtan Company, a subsidiary of China National Geological Equipment Group under Sinomach, offering critical support for the high-precision survey operations of the "Qiaoyuan Hao."
During the construction of this vessel, researchers overcame technical barriers in high-end marine survey equipment, achieving domestic independent development of all core equipment, including the marine drill rig, downhole penetration system, and samplers, with a localization rate of 100%.
This marine drill rig is the HY-300B new-generation wave compensation drill rig, an upgraded iteration launched by Zhongdizhuang Hengtan Company this year based on years of technical accumulation. The company has solved the challenge of maintaining stability in undulating sea surface conditions, making wave compensation technology more mature. This drill rig is suitable for deeper waters, can overcome higher waves, and offers more precise compensation, with ultra-high wave amplitude dynamic compensation capability. It significantly improves sampling success rates in harsh sea conditions, enabling stable operation in complex marine environments and meeting all-weather, long-cycle marine operational needs.
The research team not only overcame a series of key core technologies, such as marine precision penetration and wave compensation, achieving independent control of critical marine engineering survey equipment, but this series of drill rigs has also played a vital role in major projects such as the preliminary seabed geological survey for the Hong Kong-Zhuhai-Macao Bridge construction and the Yangjiang offshore wind farm, accumulating practical experience under complex and extreme working conditions. The new-generation HY-300B drill rig has achieved comprehensive performance upgrades based on this foundation.
In the future, Zhongdizhuang Hengtan Company will continue to deepen the development of high-end marine equipment, serving national-level marine engineering projects such as deep-sea offshore wind power and cross-sea passages.
